Hague-Dick, Archaeological site in La Hague, France.

Hague-Dick is a Bronze Age earthwork bank with a ditch that once barred the La Hague peninsula from Herqueville to the Sabine valley. Today it appears as a grassy ridge, 7–8 m wide at the base and 2 m at the top, with heights from 80 cm to 7 m; the best-preserved stretch, about 2.6 km long, runs through a field near the Château de Beaumont.

Excavations between 1951 and 2004 uncovered objects from the Bronze Age through the Middle Ages, with carbon dating pointing to construction between 900 and 800 BC. These findings indicate the structure was used and reused across many centuries.

The name Hague-Dick combines Old Norse hagi, a pasture or enclosure for cattle, with dík, a ditch or earth bank. A 1232 Vauville cartulary records it as fossatum de Haguedith, and a notary's office of Haguedic still existed in 1574. An English place called Haggedik, cited in 1327, may share the same root.

The best-preserved stretch lies in a meadow at a spot called le Petit Parc, northwest of Beaumont, on the grounds of the Château de Beaumont. There the bank stands 80 cm to 7 m high, with a base 7 to 8 m wide and a top 2 m wide. In the marshy sections, look for stone slabs or covered bridges built to let water through.

Duke Anne de Joyeuse ordered partial destruction of the structure in the 16th century, yet about 2.6 kilometers of earthwork remain visible today for study and exploration. These remains show how resilient the original construction truly was.
